Using well‐defined Zn‐ and Al‐based catalysts, highly effective and controlled ring‐opening polymerization (ROP) of the cyclic ester α‐chloro‐ε‐caprolactone (αClεCl) is discussed on page 1197 by Samuel Dagorne and co‐workers. A (salen)Al(OR) derivative proves to be an efficient catalyst for the production of chain‐length‐controlled PLLA‐ b ‐PαClεCl diblocks ‐ through sequential ROP of L‐lactide and αClεCl ‐ affording copolymers with improved thermal and biodegradable properties.
